Etiology of hepatic coccidiosis
Eimeria stiedae
clinical signs of hepatic coccidiosis
hepatomegaly, icterus, anorexia diarrhea at terminal stages
Epizootiology of hepatic coccidiosis
fecal oral transmission younger rabbits more severely affected possible dissemination via lymph or intravascular
Pathology of hepatic coccidiosis
hepatomegaly, multifocal yellowish/white spots not he liver biliary exudate, bile duct dilatation
Histopathologic lesions associated with hepatic coccidiosis
papillomatous hyperplasia of bile ducts presence of Eimeria at various life stages
Diagnosis of hepatic coccidiosis
bilirubinemia leukocytosis, anemia decreased fibrinogen Fecal exam liver microscopy
Etiology of intestinal coccidiosis
Eimeria spp.
Clinical signs of intestinal coccidiosis
Preweaning rabbits resistant diarrhea, weight loss, decreased growth rate Death due to dehydration
Epizootiology of intestinal coccidiosis
fecal oral transmission ingestion of sporocysts
Pathology of intestinal coccidiosis
white foci of necrosis on intestinal wall
Diagnosis of intestinal coccidiosis
ID of oocytes on fecal PCR
Treatment of coccidiosis
sulfaquinoxaline, strict sanitation
Etiology of cryptosporidiosis
Cryptosporidium cuniculis
Clinical signs of cryptosporidiosis
lethargy, anorexia, diarrhrea
Epizootiology of cryptosporidiosis
ingestion of sporulated oocysts shedding of oocysts 7-14 days post infection
Pathology of cryptosporidiosis
blunted villi edema of lamina propria dilation of ileal lacteals
Diagnosis of cryptosporidiosis
PCR
Treatment of cryptosporidiosis
supportive care, sanitation practices
